ABSTRACT: Spirometers are used to measure lung capacity and response of lungs and chest during physical therapy. Current spirometers available in the market are expensive and usually cost over $1,000. Due to this high cost, many physicians practicing in developing countries like India, cannot afford spirometry equipment. As a result, millions of people with chronic obstructive pulmonary disease, or COPD, are unable to be effectively monitored or treated for their disease. Thus, the development of a low cost reliable spirometer would allow these physicians to assess their patient’s pulmonary health. All these factors led to the development of a product which addresses cost issues as well as technical accuracy[1] . A computer-based miniaturized spirometer system is Designed to be realized which would use a solid state pressure sensor. A proto-type of a Computer based Spirometer system has been realized which would employ a solid state single port pressure sensor. A dedicated analog signal acquisition and processing channel has been designed and tested along with the solid-state pressure sensor. Calibration of pressure sensor for known values of applied pressure
